E. W. PETERSON ELEVATOR INSTALLATION Filed Jan. 8, 1929 Patented Mar. 25, 1930 PATENT OFFICE EARL PETERSON, OF CHICAGO, ILLINOIS ELEVATOR. INSTALLATION Application filed January 8, 1929.

My invention relates to the installation of doors in elevator shafts, and more particularly to means for protecting the door hangers from; dust and extraneous interference,

and my main object is to provide a novel cover for the hanger. compartment which is easily removable.

A further object of the invention is to so dispose the novel cover that it may be loosened for removal by a short and simple motion. 1

A still further object of the invention is to so design the cover and the receptacle therefor that the cover may be accessible for removal from a convenient position in the elevator cab.

Another object of the invention is to provide the novel cover with a bearing whereby to retain the cover compactly against the frame work of the hanger compartment, so that the cover may at no time be in the way of the cab.

Afinal, but nevertheless important object of the invention is to construct the novel cover along lines of extreme simplicity whereby to make its cost nominal and its application easy.

WVith the above objects in view and any others that may suggest themselves from the specification and claims to follow, abetter understanding of the invention. may be had by reference to the accompanying drawing, in which-' Figure l is a vertical section of a typical elevator door installation, showing the positions of the novel cover both as installed and as about to be removed;

Fig. 2 is a fragmentary elevation of the door installation at one of the upper corners, the view being directed from the right hand side of Figure 1.

Fig. 3 is an elevation of the installation on a smaller scale as viewed from the interior H of the elevator cab and Fig. 4 is a perspective view of the novel cover.

In modern elevator door installation, the space above the doors and which contains the hanger mechanism, faces the shaft. This space or compartment is usually closed to the Serial No. 331,037.

view by a cover plate, the conventional plate being one that is hinged to open outwardly. When this plate is opened, access is had for the purpose of lubricating the door hanger, and usually access for opening the plate is had by lowering the cab to a suflicient extent that a mechanic standing upon the cab may have handling access to the cover; also, thisoperation is necessary because the cover is usually much longer than the cab entrance and cannot therefore be swung out suificiently by access from within the cab. Granting that the hanger has been attended to, it is often the case that the cover is left open or isimper-fectly closed with the result that it isjarred open from the operation of the doors. In this event, the cover projects in the way of the moving cab and is apt to be damaged or even entirely broken off by the impact of the cab. It has been my intention to depart from the deficiencies of covers used in the past and to provide a cover which is efiicient and fulfills the above stated objects incvery particular.

Referring specifically to the drawing, 10 denotes as a matter of example a set of twospeed doors in a typical elevator installation. In connection with these, a simple hanger installation 11 is shown, the compartment or housing therefor being indicated at 12, and the facing plate at 13. The facing plate is coincident with the front wall of the shaft, and the cab I l moves and opens along a path in close proximity to such wall.

The housing 12 is made with conventional brackets 15 to serve as a backing for a cover or enclosure for the hange1 compartment, the novel cover being indicated at 16. As more clearly shown'in Figure 4, this cover is con structed from a length of stiff sheet metal, 53 being made with a downward hook flange 16 along its top edge and with a deflected portion 16 toward the lower edge, such edge being formed with a channel flange 16". Considering the cover as viewed from the cab, the hookflange 16 is frontally directed, while the deflected portion 16 is in a rearward direction; and the channel 16 is in. the natureof a trough and extends along the rear side of the cover.

lines in Figure 1.

The novel cover is made in a main length, indicated by the numeral 16, and with an extension17, as shown in Figure 3. The main length 16 covers the greater portion of the hanger mechanism, such portion being the one which requires the most frequent lubrication and, attention; and the extra length may be considered as covering that portion of the hanger installation which requires but occasional lubrication and attention. My reason for constructing the novel' cover plate with the main and extended sections in separate bodies is to facilitate the removal of the main and more frequently serviced portion of the cover plate by handy access from within the cab. Thus, it is not necessary to have the mechanic mount the top of. the cab and direct the operator to adjust the position of the cab to the proper level for access to the main portionjof the COVGI.

In order to install the novel cover, I form v the lower edge of the'iacingplate 13 with an up-turned hook flange 18 such flange being rearwardly directed when considered; as

viewed from the cab. It is, my intention that the cover be suspended from the-facing plate by hooking the flange 16 of the cover into the flange 13 of the facing as denoted by full By proper machine methods, the fiangesmaybe pressed whereby to engage with afairlysnug fit, so that they will not be subject to vibration yet will not require more than ordinary strength to dis- .engage them in case the cover. is to be removed. After the cover has been hooked-as described it maybe secured against accidental departure by applying screws 18 by way of holes 18 made in the cover to enter tapped holes made in the brackets 15, the application of such screws serving to dispose the cover in rigid position. The deflected portion 16 and the channel 16.ofthe cover serve to catch and confine any excess lubricating material which may be discharged from the hanger mechanism in the direction of the cab.

When the hanger mechanism is to be lubri-- cated or otherwise attended to, itis aneasy matter for the mechanic tojapproach the tention to the hanger is thus immediately had v by reason of the intimate exposure of the hanger compartment and the fact that the cover is entirely out of the way. This method of removing the main portion of the cover,

which is of alength in excess of the door openlng, actually exposes sucha length on the part of the hanger mechanism with the result that the greater or more important portion of such mechanism may be fully lubricated or otherwise serviced without the necessity of climbing upon the cab, special handling ofthe latter by the operator,and the delay so incurred. Also the removal of the cover allows clearance when hanging the doors.

After the hanger has been serviced in the manner described and the cover restored and secured in place, it will not be evident to those travelingin the cab that any special function is "suggested by the cover plate. In other words, the latter is extremely neat in appearance and in'its relation to the facing.

plate 13; and, being of excess length; in its main portion, itsends or breaks from the ex-,

tensions 17 are not visible to those. riding in thecab. Y q The method of applying the cover also enables it to be shifted sidewise by simply re- 7 moving the screws 18 in case itis not desired that the cover be ent rely removed so that but a portion of the mechanism maybe exposed ifdesired by a partial shift of the cover. 7 Also, it may beadvisabletorreversethe directionsof the co-acting hook flanges13 and" 16 whereby to'dispose the; cover exteriorly of the facing plate lS; and further, it may be] advisable to dispose the main andextended portions of the covertelescopically. However, these modifications may be but incidental to the specifications laid out for the installation in specific instances, and may be considered as secondary, since they do not es sentially depart from the spiritof my invention.

In conclusion it may be said thatthe novel' cover is an appliance of extreme simplicity, V and is capable of application without causj ing an appreciable departure from standard elevator design. The method by which it is serviced precludes the possibility of defective or insutficient mounting whereby to de-' tract from the safety factor of the appliance, since the cover is always in'full viewof the elevator operator and canfbe checked as to properinstallation immediately. "Should the cover by any'chance become damaged, it is a matter of trifling expenseand service to re-- place it by anew one.- V 7 While I have illustrated and described the invention inxthe preferred form,it will be evident that the same is capable'of many minor changes and refinementsandit is my ments as coming within the spiritand scope of the appended claims:
